Abstract

A structural component includes a first component; a second component composed of metal; and at least one connecting piece composed of metal and which penetrates the first component at least over an entire thickness of the first component, and is fixed in the first component for rotation therewith. The at least one connecting piece is connected to the second component via welding at an end facing the second component.

First claim

What is claimed is:

1. A structural component, prepared by a process comprising:
forming a first component composed of a fibre composite material by incorporating at least one connecting piece composed of metal during formation of the first component by inserting the at least one connecting piece and winding fibres of the fibre composite material around the at least one connecting piece, such that the at least one connecting piece is to penetrate through the first component at least over an entire thickness of the first component, and such that the at least one connecting piece is fixed in the first component for rotation therewith; and
arranging a second component composed of metal at one side of the first component and connecting the second component to the at least one connecting piece via a welding process.

2. The structural component of claim 1 , wherein the first component is a panel.

3. The structural component of claim 2 , wherein the second component is a panel.

4. The structural component of claim 1 , wherein the least one connecting piece is formed as one of a cylinder, a pin, and a pin with a head.

5. The structural component of claim 1 , wherein the second component is a metal sheet.

6. The structural component of claim 1 , wherein the second component is a metal disc or a metal strip.

7. The structural component of claim 1 , wherein the at least one connecting piece is connected to the first component by a material bond and/or a form fit.

8. The structural component of claim 1 , wherein the at least one connecting piece comprises a cylinder or a pin which is welded at one end to the second component.

9. The structural component of claim 1 , wherein the at least one connecting piece comprises a pin with a head which is welded to the second component at an end thereof that has no head.

10. A structural component, prepared by a process comprising:
forming a first component composed of a fibre composite material, by incorporating at least one connecting piece composed of metal during formation of the first component by inserting the at least one connecting piece and winding fibres of the fibre composite material around the at least one connecting piece, such that the at least one connecting piece is to penetrate through the first component at least over an entire thickness of the first component, and such that the at least one connecting piece is fixed in the first component for rotation therewith;
arranging a second component composed of metal at one side of the first component and connecting the second component to the at least one connecting piece via welding; and
arranging a third component composed of metal at another side of the first component and connecting the third component to the at least one connecting piece such that the first component is arranged between the second component and the third component.

11. The structural component of claim 10 , wherein the first component, the second component, and the third component each comprises a panel.

12. The structural component of claim 10 , wherein the least one connecting piece is formed as one of the cylinder, a pin, and a pin with a head.

13. The structural component of claim 10 , wherein the at least one connecting piece is connected to the first component by a material bond and/or a form fit.

14. The structural component of claim 10 , wherein the at least one connecting piece comprises a cylinder or a pin which is welded at one end to the second component.

15. The structural component of claim 10 , wherein the at least one connecting piece comprises a pin with a head which is welded to the second component at an end thereof that has no head.

16. A method for producing a structural component, comprising:
forming a first component composed of a first material by incorporating therein at least one connecting piece composed of a second material that is different than the first material during formation of the first component by inserting the at least one connecting piece and winding fibres of the fibre composite material around the at least one connecting piece, such that the at least one connecting piece is to penetrate through the first component at least over an entire thickness of the first component, and such that the at least one connecting piece is fixed in the first component for rotation therewith;
providing a second component composed of the second material; and
connecting the first component and the second component by welding the at least one connecting piece to the second component.

17. The method of claim 16 , further comprising, after forming the first component, and before connecting the first component and the second component, positioning the second component in relation to the first component.

18. The method of claim 16 , wherein the welding comprises spot welding, build-up welding, friction welding, or welding with a reactive film.

19. The method of claim 16 , wherein the first material comprises a fibre composite.

20. The method of claim 19 , wherein the second material comprises a metal.
